Am not underestimating your capacity of giving up to $500 as reward to winner on this, but I consider it more of a project research work which shouldn't involve money to earn since it's not like a normal contest everyone will take his time in applying to be eligible for win, I may be wrong though, but we have to offer things that will go far beyond the reasonable doubts of other people concerned, and if it's as exactly how being said, then I give applaud to their efforts and contributions towards this research.
